9 Claims. (Cl. 20-12) This invention relates to the building industry, and has particular reference to an improved window construction, wherein a double hung window may be resiliently mounted for easy removal of the sash, and for improved sealing against the weather.

Devices of this character have heretofore been known to the public, but the devices now known to the public leave much to be desired in the solution of the problem of weather-proofing the window yet permitting the easy removal of the sash. For example, in the devices now known to the public, comparatively rigid screws, posts, and the like, are utilized in fastening and holding the resilient members in position. This presents a difficulty in removing the sash, as the rigid screw or post element causes a binding action between the adjacent guides of the upper and lower sash. In such a construction, if an attempt is made to provide suitable clearance for removal between the adjacent sash guides, it will permit the entrance of wind and weather back of the removable sash, so that it is difiicult to properly weather-proof such a structure.

It is, therefore, an object of the invention to provide a mounting for a double hung window which is constructed and arranged so that the sash may readily be removed while at all times maintaining a close weather sealing contact between adjacent sash guides.

Another object of the invention is to provide a mounting for a weather strip and sash guide, which is very resilient and flexible, and one which permits the resiliently mounted sash guide to be moved longitudinally as well as transversely a predetermined distance during the sash installation and removal operations.

Another object of the invention is to provide a substantially free floating mounting means for a weather strip and sash guide.

Another object of the invention is to closely seal the window between the adjacent sash guides so that it is unnecessary to provide an exact fit between the sash guides and the blind stop, or between the sash guides and the trim molding.

Another object of the invention is to provide a mounting for a weather strip and sash guide which is constructed and arranged in such manner as to compensate for normal warpage of the side frames or jambs, whereby to effect a weatherproof seal at all times.

Another object of the invention is to provide a seal against air infiltration behind the sash guides by having one sash guide of each sash firmly secured against the window side jamb while having the opposite guide of the same sash resiliently mounted on two or more adjustable coil springs, which springs may be canted toward the adjacent stationary sash guide, yet permitting the supporting springs to be canted in the opposite direction at any time, when it is desired to remove the window sash.

Another object of the invention is to provide a resilient mounting means for a sash guide and weather strip, which is contructed and arranged so that increased tension may be provided on the resilient mounting, merely by rotating the same about its own axis.

Another object of the invention is to permit the removal of each sash by urging it against the spring pressure of the supporting springs until the opposite edges of the sash are free of the stationary sash guide, so that the sash may then be swung clear of the window frame.

Another object of the invention is to provide a spring mounting for a weather strip and sash guide, which evenly distributes the pressure of the spring across the entire width of the weather strip and sash guide, which insures a smoother up and down motion of the sash, while at the same time provides suflicient pressure on the sash guide to support the sash in any desired position throughout its range of travel.

Another object of the invention is to provide a weather strip and sash guide support, which may be inclined to an extreme angle to provide easier sash removal, without deforming the sash guide and weather strip at the point of support thus permitting a lighter metal to be employed in fabricating the sash guide and weather strip.

Another object of the invention is to provide a securing means for a sash guide and weather strip which makes for greatly simplified installation, in as much as the weather strip will align itself regardless of reasonable variations in the window construction. This is a great advantage to production window manufacturers and installers, as it obviates much of the tedious fitting and adjustment necessary with other types of installation.

Another object of the invention is to provide a tensioned and balanced sash guide and weather strip, which obviates the necessity of moving the side jambs in relation to the vertical center line of the sash, as is necessary with other types now known to the public. This is of great advantage in the installation of windows in older homes, where the jarnb set-over would be structurally and economically unfeasible. It is also advantageous in the manufacture and production of wood windows as their dealers would be able to stock standard sizes of window frame parts regardless of the type of weather stripping that may be used from time to time.

Another object of the invention is to provide a weather strip and sash guide assembly which permits the easy removal of the sash, but which prevents the removal of the sash from the outside when the window is closed and locked.

The foregoing and other objects and advantages of the invention will become more apparent as the description proceeds, reference being made from time to time to the accompanying drawing forming part of the within disclosure, in which drawing:

Fig. 1 is a fragmentary elevational view of a double hung window provided with the device embodying the invention.

Fig. 2 is a section taken substantially on the line 2-2 of Fig. 1.

Fig. 3 is an enlarged fragmentary detail, partly in section, illustrating one of the sash guides with the pressure pad and rotatable supporting spring mounted thereon.

Fig. 4 is a plan view with one of the spring retainers.

Fig. 5 is a side elevational view of the spring re tainer shown in Fig. 4.

Referring now more particularly to the drawing, it will be understood that in the embodiment herein disclosed, the reference character 7 indicates the lower sash and the reference character 8 indicates the upper sash of a double hung window, each sash being provided with a pane'of glass 10. The sashes 7 and 8 are mounted in a conventional window opening, which is provided with the side frames or jambs 11 and 12,trim stops 13 and 14, trim moldings 15 and 16, and blind stops 17 and 18, all of which are conventional and form no part of the invention except as combined with the elements hereinafter described.

Each sash 7 and 8 is provided with a pair of combined sash guides and weather strips 19, 20, 21, and 22. The guides 19 and 22 being securely fixed to the side jambs 11 and 12 by means of a plurality of screws 23. The guides 20 and 21 being resiliently mounted as hereinafter described. It will be noted that the fixed sash guides 19 and 22 are positioned at opposite sides of the window frame. It will also be noted that the sash guides 20 and .21 are positioned on opposite sides of said frame.

Referring to Fig. 3, it will be seen that the sash guide 21 is formed of a section of suitable material with a channel 24, the walls of which serve as a guide for the sash 7. The marginal edges of the guide 21 have return bends 25 and 26, which serve as retainers for a pressure pad 27, which is made in the form of a disc having a depressed center 28, which is provided with a screw driver slot 29, so that the pressure pad 27 may be rotated about its axis by means of a common screw driver. The guide member '21 has a cut out portion 30, which is defined by a lip 31 whichis arranged to ride in the depressed portion 28 of the pressure pad 27 and serves to maintain the pressure pad 27 against lateral movement with respect to the guide member 21. A cylindrical coil spring'32 is secured by welding, as at 33, to the pressure pad 27 and serves as a flexible ,suporting means for the guide member 21. Several of 'these pressure pads and coil springs are provided for each of the guide members 20 and 21, so that the guide members 20 and 21 have a substantially floating support. That is, they are moveable in all directions to the extent of the flexibility of the springs 32.

'I-he convolutions of the springs 32 are arranged to engage the spring retainers 34 which are constructed, as shown in Figs. 4 and 5, each retainer 34 having a flat end portion 35 with an aperture 36 therein, whereby the retainer 34 may be secured, by'nails 37, in a suitable bore 38 formed in the side jambs 11 and 12. The rotation of the pressure pad 27 causes the rotation of the coil spring 32 whereby the convolutions of the spring 32 serve as threads to move the spring 32 into and out of engagement with the web portion 35a of the retainer 34, so that any desirable degree of tension may be exerted on the spring 32. With this arrangement, it is obvious that the Weatherstrip and sash guides 20 and 21 are'resiliently mounted, so that it is only necessary to exert pressure on the sashes 7 and 8 in the direction of the resiliently mounted guide members 20 and 21, to free the opposite sides of the sash from the permanently fixed sash guides 19 and 22. Because of the natural tendency of the spring 32 to cantin one direction because of the engagement of the convolutions of the spring with the central part .35 of the spring retainer 34, the flexibly.

mounted guides 20 and 21 are constantly forced in the direction of the fixed guides 19 and 22,.whereby there is always a close contact between the two guides at the approximate side center of each window opening, as at .39

' and 40' (-Fig. 2), so that it is impossible for air to leak around the edges of the sash.

This construction also permits the easy removal of each sash as'the springs 32 will flex freely in :any direction without causing any :binding action between the moveable guides and the adjacent fixed guides. .By adjusting the tension on the springs 32,,it is possible to lower the sashes 7 and 8 between any pair of jambs .11

a and '12 regardless of mis-alignment caused by warping and the like.

. .In operation, the device functions as follows:

The Weather strip and guide members 19 and 22 are first secured to the inside faces of the side jambs 11 and 12 by means of the screws 23. Spaced holes 38 are then formed in the jambs 11 and 12, preferably in vertical alignment. The spring retainers 34 are then secured in the holes 38 by means of the nails 37. The guide member 21 for the sash 7, which previously has had assembled to it the pressure pad 27 and the springs'32, is then installed by aligning the springs 32 with the-openings 38 and rotating the springs 32 by means of a screw driver, so that the convolutions ofeach spring engages the center portion 35 of a spring retainer 34. When suitable tension is placed on the springs 32, the sash 711s positioned against 'the guide member 21 and is forced to the left so that the opposite side of the sash 7 I may be brought into contact with the channel formed in the guide member 22. The sash 8 is assembled in V the same manner.

To remove either of the sashes, it is only necessary to exert pressure against the guide member which is resiliently mounted until the opposite side of the sash can be swung free of its fixed guide member. 7
